Title: Gas replenishment method and apparatus for excimer lasers
Inventor: SANDSTROM RICHARD L
IPC: H01S3/225
Filed: 1994-08-31
Granted: 2004-03-09
Abstract: An excimer gas laser using a fluorine/krypton/neon gas mixture is provided with separate fluorine/neon and krypton/neon gas sources for use in replenishing the gas mixture. A bleed-down mechanism is also for provided for draining a portion of the gas mixture from the excimer laser. A control mechanism controls operation of the separate fluorine/neon and krypton/neon source and the bleed-down mechanism to selectively vary the gas mixture within the excimer laser to maintain an overall optimal laser efficiency. Preferably, the control system monitors operational parameters of the excim er laser including gain, wavelength, bandwidth and pulse rate, to determine whether the gas mixture within the excimer laser may have changed from an optimal mixture. The control system controls operation of the separate fluorine/neon and krypton/neon sources to compensate for changes in the operation parameters of the laser to thereby maintain high overall laser efficiency. Alternatively, gas replenishment is controlled subject to pre- determined empirically-based gas replenishment strategies.

Granted: 2007-01-30
Abstract: This invention discloses a method of authenticating a signature of a message m comprising the steps of determining a hash h(m) of the message by application of a hash function and deriving therefrom a first signature component. The signor then computes a function mathematically related to the hash of the message and applies the function to the message to obtain a second signature component, bound to the signatory. The signature components are forwarded to a recipient. The recipient then recovers from one of the signature components a message m' and computing a value of m' by applying the hash function, and determining if the value of m' and the hash h(m) embodied in the first signature component are identical whereby identity indicates an authentic signature of the message.
